Hi all can some head me in the right directin
We have a 22ft van with an East / West bed with the head of the bed at the door/ awning side and want to to fit a truema gas heater and have been that it can only be fitted if the air intake is on the opposite side which will make it hard to fit under the lift up bed is this info correct
Thanks
Greg

Gooday,
Only help I can give you is that we have had a Webasto for 7-8 years and has given us great service, you can vent it wherever, and runs on Diesel, very economical and reliable.
know lots of others with the same brand and also faultless.
Best of luck.
Only other suggestion I have is to install your hot air outlet as close as possible to the heater unit, do not be tempted to run conduit underneath as you will experience Giant heat loss, I can speak from experience.
Cheers,
Boroma604.

How was the noise from the heater.....
I've never heard one yet that didn't annoy us from even 50M away, but not knowing brands, I don't know if one brand is noisier than another ?

Hi Greg, friends of ours with a Hino Motorhome had one put in under a single bed on one side with outlet facing toward front of bus past the cupboards ,and the inlet was on the side between the beds and as a result the heater kept running , because it was not getting the warmed air to the thermostat to stop the burner . He asked me why it was staying on ,so I told him to put a hair dryer hot air ,into the intake to see if that was the problem ,and it then shut down ok .So I guess in your situation if you have the hot air coming forward into the centre of the van ,the air will not get warm enough on the other side to shut it down ,when the temp is comfortable ,so it will get hot enough , but you may have to keep shutting it down.Some others may have the answer ,as I do not have one fitted.
Regards
John

Greg
There is a requirement under the Gas Regulations and Standards for the exhaust for any gas appliance to be not within any enclosed space (ie must have adequate ventilation).
Whilst there is no enclosed annex then there should not be an issue with the gas exhaust going out the left side of the van, and in the case of the Truma heater this also includes the inlet air for the furnace.
There are a number of vans being built today that have the 3 way fridge located on the left side with the gas exhaust also on that side (my own near new Jayco being one such van) and this is not an issue until there is an enclosed annex fitted, then there has to be provision for this gas exhaust.
As for the HEATED air within the van I would recommend having the hot air outlet as far as is practicable from the cool (return) air inlet, this will ensure heated air circulating throughout the maximum area within the van, too close together and you only warm that area between the two. If you have to run ducting under the floor for this then make that the return (cool) path. I have done this for about 5 metres with a Diesel heater with success, although the end of the van furthest from the hot air outlet was still noticeably cooler than at the hot outlet (that van was 24 ft and NOT very
well insulated).
Trusting this is of assistance.
